Chemical abundances of 1111 FGK stars from the HARPS GTO planet search program IV. Carbon and C/O ratios for Galactic stellar populations and planet hosts
E. Delgado Mena, V. Adibekyan, N. C. Santos +4
[ABRIDGED]We study the carbon abundances with a twofold objective. On the one hand, we want to evaluate the behaviour of carbon in the context of Galactic chemical evolution. On th…
Oxygen abundances in G- and F-type stars from HARPS
S. Bertran de Lis, E. Delgado Mena, V. Zh. Adibekyan +2
We present a detailed and uniform study of oxygen abundance from two different oxygen lines at 6158 and 6300 in a large sample of solar-type stars. The results are used to ch…
Li abundances in F stars: planets, rotation and galactic evolution
E. Delgado Mena, S. Bertrán de Lis, V. Zh. Adibekyan +7
We find that hot jupiter host stars within the T range 5900-6300K show lower Li abundances, by 0.14 dex, than stars without detected planets. This offset has a signi…
Stars with and without planets: Where do they come from?
V. Zh. Adibekyan, J. I. Gonzalez Hernandez, E. Delgado Mena +5
A long and thorough investigation of chemical abundances of planet-hosting stars that lasted for more than a decade has finally beared fruit. We explore a sample of 148 solar-like…
On the origin of stars with and without planets. Tc trends and clues to Galactic evolution
V. Zh. Adibekyan, J. I. Gonzalez Hernandez, E. Delgado Mena +5
We explore a sample of 148 solar-like stars to search for a possible correlation between the slopes of the abundance trends versus condensation temperature (known as the Tc slope)…
